BOTTLE-CAP WRENCH Filed Feb. 10, 1951 Invenior JmrzzwZ Jazz/Z627 Allomey Patented Apr. 12, 1932 STATES SAMUEL LAWLER, F SPRING VALLEY, NEWYORK BOTTLE CAP WRENCH Application filed February 10, 1931. Serial No.514,876.

This invention relates to an improved tool or implement which may bedescribed as a wrench and which is particularly designed to expedite theremoval of a screw cap from various kinds of containers, particularlymedicine bottles of the type employing sheet metal screw caps.

It is a matter of common knowledge that these types of caps are quitedifiicult to remove and many kinds of makeshift devices and implementsare employed for forcing the cap ofi, some persons resorting to hammersand the like to expedite the cap removal, the result being distortion ofthe cap and frequent breakage of the bottle.

The present invention comprehends a simple and economical wrench in theform of a longitudinally elongated wedge shaped frame having a handle atone end, and having its side portions formed with gripping teeth toengage the rim portion of the cap to facilitate removal.

The purpose of the invention is to provide a longitudinally taperedframe which is susceptible of gripping a variety of caps of varyingsizes and diameter.

In the drawings:

Figure 1 is a top plan view of a wrench constructed in accordance withthe invention.

Figure 2 is a cross section on the line 2-2 of Figure 1.

Figure 8 is an edge elevational view.

As before implied the wrench is character'- ized primarily in the formof a longitudinally elongated frame denoted generally by the referencecharacter 4. This is formed from a single length of wire rod of suitableproportions preferably cylindrical in cross section as shown in Figure2. The frame is longitudinally elongated tapered or wedge shapeddesigned so as to accommodate different sizes of caps. It includes apair of companion side members 5 and 6 connected together by an endmember 7. At the wide end of the frame is a reduced hand grip 8 ofsuit-able shape. The inner opposed edges of the members 5 and 6d areeither serrated or corrugated to provi e ri in teeth 9 to securel on agethe flangfi p b f'tid n of the bottle cap? g In practice the frameportion of the wrench is slipped over the cap while the cap is on thebottle and the cap is wedged into the narrow end portion of the frameuntil the teeth 9 securely grips the rim portion of the cap. By thenholding the bottle with one hand, turning the wrench with the handle 8,it is easy to loosen the cap by unscrewing it.

It is thought that the description taken in connection with the drawingswill enable a .clear understanding of the invention, to be thereof toform a handle, the sides of the member being convergently arranged, across piece connecting the sides of the member together at the small endof the device, and the ends of the sides at the large end of the devicebeing curved inwardly to join the ends of the loop, whereby pressureupon the limbs of the loop will prevent the limbs of the devicespreading apart when the device is in use, and the inner walls of thesides being serrated to form gripping surfaces.

In testimony whereof I afiix my signature.

SAMUEL LAWLER.
